Old naval ships fired 11 kg cannon balls from a 240 kg cannon. It was very important to stop the recoil of the cannon, since otherwise the heavy cannon would go careening across the deck of the ship. In one design, a large spring with spring constant 2.0×104 N/m was placed behind the cannon. The other end of the spring braced against a post that was firmly anchored to the ship's frame.What was the speed of the cannon ball if the spring compressed 55 cm when the cannon was fired?

Question

Old naval ships fired 11 kg cannon balls from a 240 kg cannon. It was very important to stop the recoil of the cannon, since otherwise the heavy cannon would go careening across the deck of the ship. In one design, a large spring with spring constant 2.0×10⁴ N/m was placed behind the cannon. The other end of the spring braced against a post that was firmly anchored to the ship's frame.

What was the speed of the cannon ball if the spring compressed 55 cm when the cannon was fired?
